On the other hand, a gap c is provided between the outer peripheral surface of the seal ring 22 and the inner peripheral surface of the inner pipe 16. As a result, the seal ring 22 is prevented from being damaged due to vibration between the drawbar body 10 and the inner pipe 16.

そして前記連結パイプ17,ドローバー7及びインナパイプ16の軸芯部には、これらを軸方向に貫通する第4吸引穴a4が形成されている。この第4吸引穴a4は、前記連結パイプ17内部分、係合駆動部9内部分、ドローバー本体10内部分及びインナパイプ16内部分共に同じ径に設定されている。また、図示していないが、前記インナパイプ16の後端部16bには、吸引装置が接続されている。なお、本発明では、ドローバー7に形成された吸引穴をドローバー側吸引穴と称し、該ドローバー側吸引穴がホルダ側吸引穴に連通しているとされているが、本発明は、本実施形態のように、ドローバー7の吸引穴が連結パイプ17を介してホルダ側吸引穴に連通している場合も含む。   A fourth suction hole a4 is formed in the axial core portion of the connecting pipe 17, the draw bar 7, and the inner pipe 16 so as to penetrate them in the axial direction. The fourth suction hole a <b> 4 is set to have the same diameter in the connecting pipe 17, the engagement drive portion 9, the draw bar main body 10, and the inner pipe 16. Although not shown, a suction device is connected to the rear end portion 16 b of the inner pipe 16. In the present invention, the suction hole formed in the draw bar 7 is referred to as a draw bar side suction hole, and the draw bar side suction hole is communicated with the holder side suction hole. In this way, the case where the suction hole of the draw bar 7 communicates with the holder side suction hole via the connecting pipe 17 is also included.

また前記工具ホルダ4の刃具12の軸芯には、第1吸引穴a1が軸方向に貫通するように形成されている。また、前記ホルダ本体14には、第2吸引穴(ホルダ側吸引穴)a2が前記第1吸引穴a1と連通するように、かつ軸方向に貫通するように形成されている。さらにまた前記ホルダ本体14には第3吸引穴a3が前記第2吸引穴a2に連通するように形成されている。この第3吸引穴a3は、前記刃具12の第1吸引穴a1からの吸引空気以外の空気を吸引可能に形成され、第2吸引穴a2の流速を高めるようになっており、その実質的な通路面積を調整可能に構成されている。   Further, a first suction hole a1 is formed in the axial center of the cutting tool 12 of the tool holder 4 so as to penetrate in the axial direction. The holder main body 14 is formed with a second suction hole (holder-side suction hole) a2 so as to communicate with the first suction hole a1 and to penetrate in the axial direction. Furthermore, a third suction hole a3 is formed in the holder body 14 so as to communicate with the second suction hole a2. The third suction hole a3 is formed so as to be able to suck air other than the suction air from the first suction hole a1 of the cutting tool 12, and increases the flow velocity of the second suction hole a2, and its substantial The passage area can be adjusted.

前記第3吸引穴a3は、以下のように構成されている。ホルダ本体14の外周の、前記第2吸引穴a2に対応する部分、つまり刃具12と連結パイプ17との間の部分には環状をなすリング部材19が回動可能に、かつ止めねじ20により所望の角度位置に固定可能に装着されている。該リング部材19の内面には、軸方向前方に開口する溝状の吸込部19aが90°毎に形成されている。また前記ホルダ本体14には、連通部14cが前記各吸込部19aと前記第2吸引穴a2とを連通可能に形成されている。この吸込部19aと連通部14cとにより、前記第2吸引穴a2に前記第1吸引穴a1からの吸引空気以外の空気を吸引可能とし、該第2吸引穴a2の流速を高める第3吸引穴a3が構成されている。また、前記リング部材19の角度位置を調整することにより、前記吸込部19aと連通部14cとの連通面積、つまり前記第3吸引穴a3の実質的な通路面積を調整可能となっている。   The third suction hole a3 is configured as follows. An annular ring member 19 is rotatable at a portion corresponding to the second suction hole a2 on the outer periphery of the holder main body 14, that is, a portion between the cutting tool 12 and the connecting pipe 17, and is set by a set screw 20. It is mounted so that it can be fixed at the angular position. On the inner surface of the ring member 19, a groove-like suction portion 19a that opens axially forward is formed every 90 °. Further, the holder body 14 is formed with a communication portion 14c so that the suction portions 19a and the second suction holes a2 can communicate with each other. The suction portion 19a and the communication portion 14c allow the air to be sucked into the second suction hole a2 other than the suction air from the first suction hole a1, and the third suction hole to increase the flow rate of the second suction hole a2. a3 is configured. Further, by adjusting the angular position of the ring member 19, the communication area between the suction portion 19a and the communication portion 14c, that is, the substantial passage area of the third suction hole a3 can be adjusted.

このように本実施形態では、刃具12に第1吸引穴a1を、ホルダ本体14に第2,第3吸引穴a2及びa3を、さらにドローバー7及びインナパイプ16に第4吸引穴a4を形成し、インナパイプ16に吸引装置を接続したので、粉塵状の切削粉の吸引を簡単な構造で実現できる。   As described above, in the present embodiment, the first suction hole a1 is formed in the cutting tool 12, the second and third suction holes a2 and a3 are formed in the holder body 14, and the fourth suction hole a4 is formed in the draw bar 7 and the inner pipe 16. Since the suction device is connected to the inner pipe 16, suction of dust-like cutting powder can be realized with a simple structure.

また、ホルダ本体14に、第2吸引穴a2を形成するとともに第3吸引穴a3を形成したので、刃具の径が小さいため第1吸引穴a1の通路面積を十分に確保できない場合でも、第3吸引穴a3により、第1吸引穴a1からの吸引空気以外の空気を吸引でき、そのため第2吸引穴a2の流速を高めることができ、その結果、切削粉が工具ホルダやドローバー内に堆積するのを防止できる。   In addition, since the second suction hole a2 and the third suction hole a3 are formed in the holder main body 14, even if the passage area of the first suction hole a1 cannot be sufficiently secured because the diameter of the blade is small, the third suction hole a3 is formed. Air other than the suction air from the first suction hole a1 can be sucked by the suction hole a3, so that the flow velocity of the second suction hole a2 can be increased, and as a result, cutting powder accumulates in the tool holder and the draw bar. Can be prevented.

また、第3吸引穴a3を、ホルダ本体14に回転可能に装着されたリング部材19の吸込部19aと、該吸込部19aと前記第2吸引穴a2とを連通可能とする連通部14cとを有するものとしたので、前記リング部材19の角度位置を調整することにより、前記第3吸引穴a3の実質的な通路面積を刃具の径や切削粉の発生量に応じた面積に調整することができ、切削粉の内部堆積を防止できる。   Further, the suction portion 19a of the ring member 19 rotatably attached to the holder body 14 through the third suction hole a3, and the communication portion 14c that allows the suction portion 19a and the second suction hole a2 to communicate with each other. Therefore, by adjusting the angular position of the ring member 19, the substantial passage area of the third suction hole a3 can be adjusted to an area corresponding to the diameter of the cutting tool and the amount of generated cutting powder. It is possible to prevent internal accumulation of cutting powder.

さらにまた本実施形態では、前記ドローバー7の前部を構成する係合駆動部9の後端部9bを、後部を構成するドローバー本体10の前端部10a内に挿入し、これの内面にねじ込むことにより両者を着脱可能に接続したので、特に係合駆動部9部分の主軸内径を大きくすることなく第1吸引穴a1の径を大きく確保するとこができ、この点からも切削粉の吸引効率を高めることができる。   Furthermore, in this embodiment, the rear end portion 9b of the engagement driving portion 9 constituting the front portion of the draw bar 7 is inserted into the front end portion 10a of the draw bar main body 10 constituting the rear portion and screwed into the inner surface thereof. Since both of them are detachably connected to each other, it is possible to secure a large diameter of the first suction hole a1 without particularly increasing the inner diameter of the main shaft of the engagement drive section 9, and also from this point, the suction efficiency of the cutting powder is improved. Can be increased.

ちなみに、係合駆動部9の後端部9bをドローバー本体10の先端部10aに被せてねじ込む構造とした場合、第4吸引穴a4の径を同じとしても、係合駆動部9の後端部の径が大きくなり、その外側に係合爪11を配設する構造上、主軸の貫通穴径、ひいては主軸外径が大きくなる。   Incidentally, when the rear end portion 9b of the engagement drive portion 9 is screwed by being put on the front end portion 10a of the draw bar body 10, the rear end portion of the engagement drive portion 9 is provided even if the diameter of the fourth suction hole a4 is the same. And the diameter of the through hole of the main shaft and thus the outer diameter of the main shaft are increased.

また、前記インナパイプ16と前記ドローバー本体10の後端部10bとの間にシール機構21を設けたので、外部から空気がインナパイプ16内に吸引されるのを回避することができ、この点からも切削粉の回収効率を高めることができる。   Further, since the seal mechanism 21 is provided between the inner pipe 16 and the rear end portion 10b of the draw bar main body 10, it is possible to prevent air from being sucked into the inner pipe 16 from the outside. Therefore, the cutting powder recovery efficiency can be increased.

また前記シール機構21を、前記ドローバー本体10の後端部10bの外周面に摺接するシールリング22を前記インナパイプ16の段部16cに圧接させる弾性部材製の押圧リング23を設けたので、該弾性部材の弾性力により前記シールリング22の端面を前記段部16cに常時圧接させるとともに内周面をドローバー本体10の外周面に摺接させることができ、これにより外部空気の進入をより確実に防止できる。一方、前記シールリング22の外周面とインナパイプ16の内周面との間には隙間cを設けたので、ドローバー本体10とインナパイプ16との間を振れによりシールリング22が損傷するのを回避できる。   Further, since the seal mechanism 21 is provided with a pressing ring 23 made of an elastic member that presses the seal ring 22 slidably contacting the outer peripheral surface of the rear end portion 10b of the draw bar main body 10 to the step portion 16c of the inner pipe 16, The end face of the seal ring 22 can always be in pressure contact with the stepped portion 16c by the elastic force of the elastic member, and the inner peripheral surface can be slidably contacted with the outer peripheral surface of the draw bar body 10, thereby making it possible to more reliably enter the outside air. Can be prevented. On the other hand, since the gap c is provided between the outer peripheral surface of the seal ring 22 and the inner peripheral surface of the inner pipe 16, the seal ring 22 may be damaged due to the vibration between the draw bar body 10 and the inner pipe 16. Can be avoided.
